EDGAR I-IATTON, OF HAVANA, ILLINOIS, ASSIG-NOR OF ONE-FOURTH T0 EDWARDJ. KRAMPFF AND ONE-FOURTH TO SAMUEL F. KYLE, BOTH OF HAVANA, ILLINOIS.

ICE-CUTTING MACHINE.

To all whom it may concern:

Be it known that I, EDGAR HATTON, a citizen of the United States,residing at Havana, in the county of Mason and State of Illinois, haveinvented certain new and useful Improvements in Ice-Cutting Machines, ofwhich the following is a specification.

This invention has relation to certain new and useful improvements inice cutting machines and has for its object to provide a machine forharvesting ice whereby the ice may be rapidly cut into blocks of apredetermined size, by means of a circular saw rotatably mounted in asuitable wheeled frame, said saw being driven by means of suitableconnections whereby the power is transmitted from the wheels.

A further object is to provide new and novel means for transmitting therotary movement to the saw from the drive wheels.

A further object is to provide an adjustable ice cutting saw, said sawbeing longitudinally movable with relation to the supporting framewhereby the driving belt or chain may be tightened.

A still further object is to provide suitable means for elevating thesaw above the surface of the ice field.

'With these and other objects in view, the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and particularly pointed out in the appended claims, itbeing understood that changes in the specific structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

In the drawings forming a part of this specification and in which likenumerals of reference indicate similar parts in the several views,Figure 1 is a top plan view of an ice cutting machine embodying myimprovements. Fig. 2 is a side elevation showing the machine inoperative position on the ice field. Fig. 3 is a section taken on theline 3-3 of Fig. 1. Fig. 4 is a section taken on the line 44 of'Fig. 1.Fig. 5 is an enlarged elevation of the rear end of the machine, showingthe saw elevated above the ice surface. Fig. 6 is a detailed sectionillustrating the means for tightening the driving belt.

Referring to the drawings 5 indicates a Specification of Letters Patent.

wheel supported frame, the rear portion of which converges as shown at 6and is extended in parallel to provide the supporting arms 7. This frameis constructed of bar metal or angle iron and a wheel shaft 8 is rigidlysecured in the forward ends thereof.

Drive wheels 9 are revolubly mounted upon the shaft 8 and are securedthereon against longitudinal movement by means of the collars 10 whichare secured to the shaft by means of set screws 11.

A brace bar 12 connects the rear converging portion of the frame andshaft supporting bars 13 are secured to the bar 12 and the shaft 8. Inthe bars 13 a transversely positioned shaft 14 is rotatably mounted andcarries the pinions 15 which mesh with an internal gear 16 on each ofthe wheels 9. The shaft 14 also carries a gear 17 intermediate of itsends which is engaged with a pinion 18 disposed on the shaft 8. Thepinion 18 is integrally formed with a sleeve 19 upon which a band wheel20 is mounted. The wheel 20 is rigidly secured upon the sleeve by meansof the set screw 21, which extends through the sleeve and has its enddisposed in a circumferential groove in the shaft 8.

In the rear parallel arms 7 a transverse shaft 22 is rotatably mountedwhich carries a band wheel 23. This wheel is disposed in longitudinalalinement with the wheel 20, said wheels being connected by means of adriving belt 24. The extremities of the arms 7 are connected by a bar25, thus forming a very rigid supporting frame. Blocks 26 are disposedupon the outer faces of the arms 7 and depend below the same. In thelower ends of the blocks the shaft 22 is disposed, and bolts 27adjustably secure the blocks to the arms. These bolts extend through theshort slots 28 in the arms, and are movable therein when the adjustingscrew 29 which engages with one side of the block is turned. Thus theshaft 22 may be moved longitudinally in the frame and secured in itsadjusted position by tightening the nuts upon the ends of the bolts 27.Upon the shaft 22 and exteriorly of the arm 7 a circular saw 30 ismounted and is longitudinally adjustable thereon. The saw is secured initsadjusted position by means of the set screw 31, whereby ice blocks ofvarious widths may be cut. Rigidly secured to the shaft adjacent to thesaw there is a shield 32, the forward end of which is transverselycurved as shown at 33. I11 this manner the saw is protected fromcontacting with obstructions which may lie in its path of movement.

Upon the rear transverse bar 25 of the frame an L shaped arm 34 istransversely disposed, and is pivoted to the center of the bar by meansof the short headed bolt 35. A bolt 36 is removably positioned throughthe bar 25 adjacent to one end thereof and extends through thehorizontal part of the arm 34: to secure the arm in position, for whichpurpose a nut 37 is threaded on the outer end of the bolt. Upon thelower end of the vertical part of the arm 3& a disk 38 is secured and isadapted to be positioned in the cut or channel previously made by thesaw 30. Thus the width of the ice blocks which is determined byadjusting the saw blade of the shaft 22 may be uniform. The blade 30 maybe entirely removed from the shaft and positioned upon the opposite endthereof, while the disk 38 may also be placed on the opposite side ofthe machine by removing the arm 34 and turning it over.

The drive wheels 9 are each provided with the teeth or spurs 40 whichproject from the tread of the wheels and engage with the ice surface toprevent skidding of the machine. Secured to the ends of the shaft 8there is a yoke 39, to the forward end of which a draft bar 41 issecured. Shafts may be connected to the front end of the yoke 39 inplace of the draw bar, if desired, this being a mechanical equivalentwhich it is not believed necessary to illustrate.

From the foregoing it will be seen that I have provided an iceharvesting machine of comparatively simple construction, the variousparts of which are so formed as to render its operation very simple andefiicient.

' A cam lever 42 is pivoted upon the rear bar 25 of the frame, andduring the operation of the machine is disposed in the position shown inFig. 2. l/Vhen it is desired to raise the saw 30 above the ice field,this lever is thrown rearwardly, the cam portion of which engages withthe surface of the ice, and elevates the frame, saw 30 and guide disk38, thus allowing the machine to be freely moved from place to place.

By the use of a machine constructed as above set forth the ice may beeasily and quickly cut with little or no difficulty in the operation ofthe machine.

It will be understood that any desirable number of saws may be utilizedin this machine if found desirable.
